Zinsser Cover Stain Oil-Based Primer Spray, 13 oz.

Zinsser Cover Stain Oil-Based Primer Spray is a professional-grade aerosol primer designed to seal and block the toughest stains—inside or out. Its high-hiding, oil-based formula penetrates and locks down tannin, water, smoke and nicotine marks while providing excellent adhesion for topcoats. Fast-drying and sandable, it eliminates the need for sanding between coats, making it ideal for new construction, remodeling or quick-turn small projects.
